USA lost unexploded nuclear bomb in Japanese waters

World War 3: Unexploded US nuclear weapon hiding beneath Japanese waters ‘covered up’  https://www.express.co.uk/news/world/1166479/world-war-3-nuclear-bomb-japan-philippine-sea-us-soviet-union-cold-war-sptWORLD WAR 3 could have erupted after the United States Navy accidentally dropped a nuclear bomb in Japanese waters – and it is still there today. by CALLUM HOARE, Aug 18, 2019. On December 5, 1965, just three years after the Cuban Missile Crisis pushed Cold War tensions to the limits, the US made a monumental mistake during a training exercise. A United States Navy Douglas A-4E Skyhawk attack aircraft fell off the side of aircraft carrier USS Ticonderoga while sailing through the Philippine Sea. The pilot, Lieutenant Douglas M Webster, the plane, and the B43 nuclear bomb on board all fell into the water, 68 miles from the coast of Kikai Island, Japan.

However, it was not until 1989 that the Pentagon admitted the loss of a one-megaton hydrogen bomb.

The revelation inspired a diplomatic inquiry from Japan, however, neither the weapon, or the pilot, was ever recovered.The incident, the most serious involving nuclear weapons in the Navy’s history, showed that US warships carried atomic weapons into Japanese ports in violation of policy, according to researchers.

Japanese law banned ships carrying nuclear weapons from sailing in its territorial waters or calling on its ports following the terrible Hiroshima and Nagasaki incidents.

However, the US warship routinely docked in Japan.

William M. Arkin of the liberal Institute for Policy Studies claimed in 1989: “For 24 years, the US Navy has covered up the most politically sensitive accident that has ever taken place.

“The Navy kept the true details of this accident a secret not only because it demonstrates their disregard for the treaty stipulations of foreign governments but because of the questions it raises about nuclear weapons aboard ships in Vietnam.”

The event was highly sensitive, with Japan being the only country to ever be attacked with nuclear weapons at the end of World War 2.

On September 8, 1951, 49 nations drew a line under the devastating event and signed the Treaty of San Francisco – also known as the Treaty of Peace with Japan.

The document officially ended US-led occupation of Japan and marked the start of re-establishing relations with the allied powers.

Meanwhile, In 1965, the US was arguably at the height of tensions with the Soviet Union.

Not only did the accident threaten to spoil already tenuous relations with Japan, but it would have also have given the USSR an excuse to start a nuclear war.

Despite the worrying claims, the US Navy confirmed inn 1989 that the waters were too deep for the weapon to pose a threat.

Worryingly though, it would not be the last of the nuclear gaffes for America. On January 17, 1966, a B-52G USAF bomber collided with a KC-135 tanker during a refuelling mission at 31,000 feet over the Mediterranean Sea.

During the crash, three MK28-type hydrogen bombs headed for land in the small fishing village of Palomares in Almeria, Spain.

Worse still, the explosives in two of the weapons detonated on impact, contaminating the surrounding area of almost one square mile with plutonium.

The fourth sunk off the coast of Spain and was recovered three months later.

Confusion and secrecy following Russian explosion, backflip on evacuation of village

Russian military orders village evacuation, then cancels it, following explosion that killed five nuclear scientists, Secrecy surrounding an explosion that killed five nuclear scientists and caused a spike in radiation levels has sparked fears of a cover-up in Russia, with authorities backflipping on orders to evacuate a nearby village. https://www.abc.net.au/news/2019-08-14/russian-nuclear-explosion-mystery/11411470

Key points:

  • Medics who treated victims of an accident have been sent to Moscow for medical examination
  • Russia’s state weather service said radiation levels spiked in Severodvinsk by up to 16 times
  • Many Russians spoke angrily on social media of misleading reports reminiscent of Chernobyl

The explosion took place on Thursday at a naval weapons range on the coast of the White Sea in northern Russia.

State nuclear agency Rosatom said the accident occurred during a rocket test on a sea platform.

The rocket’s fuel caught fire after the test, causing it to detonate, it said in a statement carried by Russian news agencies.

Two days later, after a spike in radiation levels was reported, Rosatom conceded the accident involved nuclear materials.

On Tuesday (local time), the Russian military ordered residents of the small village of Nyonoksa to temporarily evacuate, citing unspecified activities at the nearby navy testing range.

But a few hours later, it said the planned activities were cancelled and told the villagers they could go back to their homes, said Ksenia Yudina, a spokeswoman for the Severodvinsk regional administration.

Local media in Severodvinsk said Nyonoksa residents regularly received similar temporary evacuation orders, usually timed to tests at the range.

Russia’s state weather service said radiation levels spiked in the Russian city of Severodvinsk, about 30 kilometres west of Nyonoksa, by up to 16 times following the explosion.

Emergency officials issued a warning to all workers to stay indoors and close the windows, while spooked residents rushed to buy iodide, which can help limit the damage from exposure to radiation.

‘People need reliable information’

Many Russians spoke angrily on social media of misleading reports reminiscent of the lethal delays in acknowledging the Chernobyl accident three decades ago.

US experts said they suspected the cause was a botched test of a nuclear-powered cruise missile commissioned by President Vladimir Putin.

Boris L Vishnevsky, a member of the St. Petersburg City Council, told the New York Times that dozens of people had called asking for clarification about radiation risks.

“People need reliable information,” Mr Vishnevsky told the Times.

“And if the authorities think there is no danger, and nothing needs to be done, let them announce this formally so people don’t worry.”

The five scientists that died in the explosion were buried Monday in the closed city of Sarov — which houses a nuclear research facility and is surrounded by fences patrolled by the military.

While hailing the deceased as the “pride of the atomic sector”, Rosatom head Alexei Likhachev pledged to continue developing new weapons. “The best tribute to them will be our continued work on new models of weapons, which will definitely be carried out to the end,” Mr Likhachev was quoted as saying by RIA news agency.

Medics who treated victims sent to Moscow

Medics who treated the victims of an accident were sent to Moscow for medical examination, TASS news agency cited an unnamed medical source as saying on Tuesday.

The medics sent to Moscow have signed an agreement promising not to divulge information about the incident, TASS cited the source as saying.

US President Donald Trump said on Twitter on Monday the United States was “learning much” from the explosion and the United States had “similar, though more advanced, technology”.

He said Russians were worried about the air quality around the facility and far beyond, a situation he described as “Not good!”

But when asked about his comments on Tuesday, the Kremlin said it, not the United States, was out in front when it came to developing new nuclear weapons.

“Our president has repeatedly said that Russian engineering in this sector significantly outstrips the level that other countries have managed to reach for the moment, and it is fairly unique,” Kremlin spokesman Dmitry Peskov said.Mr Putin used his state-of-the nation speech in 2018 to unveil what he described as a raft of invincible new nuclear weapons, including a nuclear-powered cruise missile, an underwater nuclear-powered drone, and a laser weapon.

Tensions between Moscow and Washington over arms control have been exacerbated by the demise this month of a landmark nuclear treaty.

‘Dirty bomb’: Mystery Russian ‘superweapon’ kills five

An on-board reactor would give an engine almost unlimited range. In the case of a guided cruise missile, it could circle the world before receiving orders to attack from out of the blue.

But they’re not easy to control.

They operate at extremely high temperatures. They use explosive fuels, such as liquid hydrogen. And any accident could have devastating, long-lasting effects.

Putin’s silence on mysterious radiation accident

Russia nuclear leak: Mysterious footage of hazmat officials escalates radiation panic https://www.express.co.uk/news/world/1164125/Russia-nuclear-leak-radiation-Putin-iodine-hazmat

CHILLING footage from Russia has intensified fears of a nuclear radiation accident after ambulances were spotted lined with protective chemical sheets and hospitals workers were seen wearing hazmat suits.

By OLI SMITH, Sun, Aug 11, 2019  Russian President Vladimir Putin has remained silent, amid growing speculation that a nuclear missile accident has caused a dangerous radiation leak at a naval base. The Kremlin have confirmed that a “rocket engine explosion” at the Archangelsk base in northern Russia killed five people and injured three. Last night, Russia’s nuclear energy agency Rostam admitted that they had been involved in the aftermath of the incident, raising concern of a radiation leak.

Rostam added that the explosion took place during the testing of an “isotope power source”.

The official said five of its employees had died as a result of the accident and three more were being treated for burns.

However, the extent of the incident and threat of radiation  has not been disclosed, amid growing global concern.

The Archangelsk naval base has been placed under emergency lockdown for a month, with the nearby White Sea also closed to commercial shipping.

sudden radiation spike detected in the region following the explosion prompted the initial speculation that the incident was related to a nuclear missile test.

The radiation level was recorded as 20 times higher than the normal level in the nearby city of Severodvinsk.

This has been reinforced by chilling footage filmed in the aftermath of the incident.

One video showed hospital workers wearing hazmat suits while they loaded the injured into an ambulance. Another terrifying video revealed a security escort of ambulances transporting the injured to Moscow.

In this footage, one of the ambulance is clearly coated in a chemical protection film.

A defence ministry source said that the worker’s clothes had been burned as soon as they were hospitalised with suspected radiation. Experts have linked the incident to the testing of the new nuclear-powered cruise missile Burevestnik mentioned during a speech by Vladimir Putin last year.

Local people have reportedly been urged to take precautions against radiation, with children from local kindergartens taken indoors after the blast.

There has also been a rush to buy iodine in Russia’s far north.

Russian expert Dr Mark Galeotti said the incident was “clearly a bigger issue than the Russians are letting on”.

He told the BBC: “Despite what the Kremlin have said, there must have been some sort of radiation leak – and they want people to not just stay out of harm’s way, but also don’t want people coming to the site with Geiger Counters.”

Five people were killed following Russian rocket explosion

Russia explosion: Five confirmed dead in rocket blast,  BBC 10 Aug 19, Five people were killed and three injured following a rocket explosion on a naval test range in Russia on Thursday, state nuclear company Rosatom confirmed.

Rostacom said the accident occurred during tests on a liquid propellant rocket engine.

The three injured staff members suffered serious burns in the accident.

Authorities had previously said that two people died and six were injured in the blast at the site in Nyonoksa.

The company told Russian media that its engineering and technical team had been working on the “isotope power source” for the propulsion system.

The Nyonoksa site carries out tests for virtually every missile system used by the Russian navy, including sea-launched intercontinental ballistic missiles, cruise missiles and anti-aircraft missiles.

Authorities in Severodvink, 47km (29 miles) east of Nyonska said that radiation levels shortly after the blast were higher than normal for about 40 minutes but returned to normal……..

Test rocket explosion causes radiation spike in northern Russian city

Test rocket explosion causes radiation spike in northern Russian city, killing two,  https://thenewdaily.com.au/news/world/2019/08/09/rocket-radiation-explosion-russia/?fbclid=IwAR1udqv3rSjTDZE5hZpDHPDo-r7Q-zPhdnuvA-Ejqwu4iButecBmHPW2QdU    Locals have been urged to take iodine tablets and stay indoors after a liquid-propellant rocket engine exploded at a nuclear test site, spiking radiation levels, killing two people and injuring another six.

Greenpeace cited data from the Emergencies Ministry that it said showed radiation levels had risen 20 times above the normal level in Severodvinsk, which is about 30 kilometres from Nyonoksa.

The environmental group said it had appealed to Russia’s consumer watchdog to establish how high radiation had risen, whether it posed a health risk to people and what had actually caused the spike.
According to Norway’s Barents Observer, the explosion happened about 9am on Thursday local time.

The paper reported the site is used for the testing of liquid-fuelled engines of ballistic missiles “for strategic nuclear-powered submarines”.

Authorities in Severodvinsk, which has a population of 185,000, reported the spike, forcing a bay in the White Sea to shut down to shipping.

“A short-term rise in background radiation was recorded at 12 o’clock in Severodvinsk,” Ksenia Yudina said on Thursday local time.   However, Russia’s defence ministry was quoted earlier by state media as saying radiation was normal.

Explosion at Russian missile test, kills two, releases spike of radiation

Radiation spike reported after rocket engine explosion during Russian missile test https://www.independent.co.uk/news/world/europe/russia-radiation-spike-explosion-rocket-engine-missile-test-latest-a9046721.html  

Two killed and four injured after blast, defence ministry say, A short-term spike in radiation levels has been recorded after a rocket engine exploded during a test in Russia, regional authorities said.Moscow’s defence ministry said two were killed and four others wounded after the blast at a military shooting range in the northwestern region of Arkhangelsk.

The ministry said there was no release of radioactivity or any toxic substances.

However, Ksenia Yudina, a spokeswoman for the city of Severodvinsk, which has a population of around 185,000, said: “A short-term rise in background radiation was recorded at 12 o’clock in Severodvinsk.”

The defence ministry confirmed six servicemen and civilian engineers were injured, and two died of their injuries. It said the explosion took place during the test of a liquid-propellant rocket engine.

City officials said background radiation levels had fully “normalised”.

An Arkhangelsk port official said the Dvina Bay area of the White Sea would be closed off to shipping for a month following the explosion, the Interfax news agency reported.

The rocket engine explosion occurred at a weapons testing area near the village of Nyonoksa in the Arkhangelsk region, 800 miles north of Moscow, said the Interfax news agency.

Russian media said an area near Nyonoksa is used for tests on weapons including ballistic and cruise missiles used by the navy.

It came two days after 16,500 people were forced to flee their homes when massive blasts rocked an arms depot in Siberia.

Powerful explosions went on for about 16 hours, killing one person and injuring 13.

The nuclear disasters that we don’t hear about – The Kyshtym Disaster

5 Unknown Nuclear Disasters: Chernobyl Is Far from the Only One, Chernobyl is not the world’s only nuclear disaster, there are plenty of others to keep you up at night., Interesting Engineering, By  

The Kyshtym Disaster

In September 1957, Ozyorsk, Russia was a closed city, built around the Mayak plant which produced plutonium for both nuclear weapons and fuel.

After scrambling to build the Mayak plant between 1945 and 1948, all six of its reactors initially dumped high-level radioactive waste directly into Lake Kyzyltash. When it became contaminated, they moved on to dumping into Lake Karachay, which also became contaminated.

In 1968, the Soviet government disguised the EURT area by creating East Ural Nature Reserve, with access allowed to only authorized personnel. Documents describing the disaster were only declassified in 1989.

On the International Nuclear Event Scale (INES), Kyshtym is rated a 6, making it the third-most serious nuclear accident behind only the Fukushima Daiichi nuclear disaster and the Chernobyl disaster, which are both Level 7

In 1953, workers built a storage facility for liquid nuclear waste, but that waste was being heated by residual decay heat from the nuclear reaction. The coolers around one of the tanks failed, and on September 29, 1957, that tank exploded with the force of between 70 to 100 tons of TNT.

While there were no immediate casualties, the explosion released an estimated 20 MCi (800 PBq) of radioactivity into the air. A plume containing 2 MCi (80 PBq) of radionuclides, primarily caesium-137 and strontium-90, moved toward the northeast and contaminated an area of more than 52,000 square kilometers (20,000 sq miles).

At least 270,000 people lived in that area, which is referred to as the East-Ural Radioactive Trace (EURT).

In an attempt to maintain secrecy, no evacuation was ordered, but a week later, on October 6, 1957, 10,000 people were removed from their homes.

Estimates of the death toll caused by the accident go from 200 to more than 8,000, depending on the study. A 2001 work stated that the accident caused 66 diagnosed cases of chronic radiation syndrome.

Amazingly, it wasn’t until 18 years later, in 1976, that the full scope of the disaster was disclosed by Zhores Medvedev in the publication the New Scientist.

In 1968, the Soviet government disguised the EURT area by creating East Ural Nature Reserve, with access allowed to only authorized personnel. Documents describing the disaster were only declassified in 1989.

The nuclear disasters we don’t hear about – The Windscale Fire

Windscale: Britain’s Biggest Nuclear Disaster – Part 01

5 Unknown Nuclear Disasters: Chernobyl Is Far from the Only One, Chernobyl is not the world’s only nuclear disaster, there are plenty of others to keep you up at night., Interesting Engineering, By  

The Windscale Fire

Less than two weeks after Kyshtym, a fire broke out in Unit 1 of the two reactors at the Windscale facility located in what is now known as Sellafield, Cumbria UK.

The two reactors were created because of Britain’s need for an atomic weapon following World War II. Determining that a uranium enrichment plant would cost ten times as much to produce the same number of atomic bombs as a nuclear reactor, the decision was made to build a nuclear reactor that would produce plutonium.

The cores of the reactors were comprised of a large block of graphite, with horizontal channels drilled through it for the fuel cartridges. Each cartridge consisted of a 12-inch-long (30 centimeters) uranium rod encased in aluminum.

The reactor was cooled by convection through a 400-foot (120 m) tall chimney. When Winston Churchill committed the UK to create a hydrogen bomb, the fuel loads at Windscale were modified to produce tritium, but this also meant that the core became hotter.

On the morning of October 10, 1957, the core began to uncontrollably heat, eventually reaching 400 degrees C. Cooling fans were brought in to increase the airflow, but just worsened the problem. It was then that operators realized that the core was on fire.

Workers tried dousing the core first in carbon dioxide, then in water, but both proved ineffective. What finally worked was cutting off air to the reactor building, which starved the fire.

The fire caused the release of radioactive radionuclides across the UK and Europe, including an estimated 740 terabecquerels (20,000 curies) of iodine-131, 22 TBq (594 curies) of caesium-137 and 12,000 TBq (324,000 curies) of xenon-133.

By comparison, the 1986 Chernobyl explosion released far more, and the Three Mile Island accident in 1979 in the U.S. released 25 times more xenon-135 than Windscale, but less iodine, caesium, and strontium. The atmospheric release of xenon-133 by the Fukushima Daiichi nuclear disaster was similar to that released at Chernobyl, and thus, high above what the Windscale fire released.

There were no evacuations of the surrounding area, but it has been estimated that the incident caused 240 additional cancer cases. For a month after the accident, milk coming from 500 square kilometers (190 sq mi) of the nearby countryside was destroyed.

The reactor tank has remained sealed since the accident and still contains about 15 tons of uranium fuel. The reactor core is still slightly warm due to continuing nuclear reactions. It is not scheduled for final decommissioning until 2037. On the International Nuclear Event Scale, Windscale ranks at level 5………. https://interestingengineering.com/5-unknown-nuclear-disasters-chernobyl-is-far-from-the-only-one

The nuclear accidents we don’t hear about – Soviet Submarine K-19

5 Unknown Nuclear Disasters: Chernobyl Is Far from the Only One, Chernobyl is not the world’s only nuclear disaster, there are plenty of others to keep you up at night., Interesting Engineering, By  

Soviet Submarine K-19

K-19 was one of what the Soviets called their Project 658-class submarines, while NATO called them Hotel-class. They were the first generation of nuclear submarines equipped with nuclear ballistic missiles.

Commissioned on April 30, 1961, K-19 was snake bit from the start. On its initial voyage, on July 4, 1961, it was conducting exercises off the coast of Greenland when suddenly, pressure in the reactor’s cooling system dropped to zero due to a leak.

The emergency SCRAM system immediately inserted the control rods, but due to decay heat, the reactor’s temperature rose to 800 degrees C (1,470 degrees F). The accident released steam containing fission products throughout the ship through the ventilation system.

The captain ordered the ship’s engineering crew to fabricate a new cooling system, but this required them to work within the radioactive area. The jury-rigged cooling water system prevented a complete meltdown of the reactor core.

American warships nearby had picked up K-19’s distress call and offered to help, but K-19’s captain, fearful of giving away Soviet military secrets, refused. Instead, K-19 sailed to meet up with a diesel-powered Soviet submarine. The accident had irradiated K-19’s entire crew, as well as the ship and some of her ballistic missiles.

Within a month, all eight members of the ship’s engineering crew died of radiation exposure. They are Boris KorchilovBoris RyzhikovYuriy OrdochkinEvgeny KashenkovSemyon PenkovNicolai SavkinValery Charitonov, and Yuriy Povstyev.

Within the next two years, 15 other sailors died of radiation-related illnesses.

Towed into port, K-19 contaminated a 700 meter (2,300 feet) wide area, and the repair crews who worked on her. Eventually, the Soviet Navy dumped the damaged reactor into the Kara Sea.

The 2002 movie K-19: the Windowmaker, which starred Harrison Ford and Liam Neeson, is based on the K-19 disaster….. https://interestingengineering.com/5-unknown-nuclear-disasters-chernobyl-is-far-from-the-only-one
